Where else can we start other than the horror show that was VAR at Wembley? The system has been used with mixed success so far in the FA Cup, but this was it at its very worst. It was farcical.

The match was fragmented, players and fans couldn't celebrate goals as every one was being reviewed by the referee and the VAR team. The free flowing nature of football was not there.

If the decisions that are being produced by the process are correct then at least the powers that be can point to that, but the decision for Erik Lamela's chalked off goal was as dubious as they come.

Both Fernando Llorente and Rochdale defender Harrison McGahey were vying for the ball and pulled at each other, but it was the Spaniard who was penalised. Then Lucas Moura got knocked over in the box, but the VAR team said no penalty and then Heung-Min Son's scored penalty was struck off for his stuttering run-up, although it was unclear whether that was a referee or VAR decision.

Ultimately it was just confusing. Nobody in the ground or at home knew what was going on, the referee never went over to a monitor to get his own take on the decision and it was just a mess from start to finish.

"The first half was a little bit embarrassing for everyone. I think it's difficult to keep focus on playing football. I am not sure that that system is going to help. I love the football as football was born. That is why we love the game that we know," he said.

"I think football, we are talking about emotion, the context of emotion. If we are going to kill the emotion then the fans, the people who love football, I don't think are so happy about what they saw today.

"We have the best referees in Europe and the world. We don't need too much. And then I think football is about making mistakes. Like us, we make a mistake, the players make a mistake and the referee can make a mistake. We are not going to help the football and we are going to change the game that we love."

Multi-skilled Lucas is certainly no Nkoudou

Apart from having no end product, Georges-Kevin Nkoudou's biggest problem was that he was one-dimensional, hugged the touchline and the match action would often pass him by in his few cameo appearances.

Lucas Moura is clearly a player from a higher shelf in the football store than the young, raw Frenchman, but most importantly he's got so many strings to his bow.

He can fly down the right wing of course, but he can also switch into the middle, driving through the centre of the pitch with strength, pace and trickery and he can also pop up on the opposite flank.

The former PSG star sliced apart Rochdale with two superb assists and could have earned that first half penalty.

Of course the opponents are currently at the bottom of League One and there are sterner tests to come, but the match was still proof that the Brazilian is getting fitter with every passing match and he offers a varied blend of skills that nobody else possesses in Pochettino's squad.

The Brazil international has settled in well and his team-mates trust him with the ball. The Spurs boss said he wanted to bring in a January signing so they could adapt early for next season and be involved in the full pre-season, but Lucas looks like he could yet play a big part in the rest of this campaign.

Son's confidence booster

This was a night that Heung-Min Son needed. The South Korean had lost that infectious grin in the previous three or four matches. He's had another fantastic season but whether it was through a touch of fatigue or simply the difficulty in keeping up such a high level, Son's performances had dropped slightly and he had lost his spot to Erik Lamela.

He scored goals aplenty in the FA Cup last season and it was the same competition that sparked him back to life in the snow at Wembley.

His first goal was classic Son, shifting the ball inside before curling it into the bottom corner.

Then came that struck off penalty, with the South Korean's stuttering run-up deemed to be unsporting conduct. It was unclear in the aftermath whether the penalty should have been retaken rather than just struck off. The 6-1 result ensured that wasn't investigated in too much detail at the end of the match though.

The attacker set up Llorente with his hat-trick goal with a pinpoint cross before netting himself. Son's second goal was his 13th in all competitions this season and he was grinning broadly, even taking the mickey out of the night's madness by doing the referee's VAR symbol with his fingers after one of Llorente's goals.

The attacking midfield trio were all brilliant on the night and the final part of the triumvirate was Erik Lamela.

It's been a long, long road back for the Argentine after those 13 months out with hip problems. He and many others doubted if he would ever play football again.

But Pochettino has stuck with his compatriot, never rushing him back into first team action and trusting him to carry out his philosophy on the pitch - the Spurs boss has previously said Lamela was the first player to get exactly what he was trying to instil in the players when he arrived back in 2014.

The midfielder started against both Crystal Palace and Rochdale within three days of each other this week, showing his match fitness is getting back to his pre-injury levels.

Against Rochdale, he set the tempo as usual, he should have had that early goal and provided two great assists to add to his collection since returning.

Lamela will always have his critics, those who can't see in him what Pochettino does, but he's playing his way towards a new contract to replace the one that ends next summer - albeit with an option for another year. The Spurs boss feels he is just too important to let go.

Fernando Llorente celebrates scoring his second goal

A big night for Fernando

The writing appeared to be on the wall for Fernando Llorente. The goals weren't coming, the performances were laboured, even against League One sides and he just couldn't fit into Tottenham's style of play.

At Wembley on Wednesday night it all came good. With that energetic trio buzzing about behind him and pulling the strings, Llorente rediscovered his scoring touch with aplomb two days after his 33rd birthday.

It was the perfect hat-trick as well, right foot, left foot and a header.

Pochettino finally admitted he had been disappointed with the World Cup winner's start to life at Spurs and his hopes that this is the turning point.

"I think it's important. I am so happy for him, all the people are happy for him. Of course I was disappointed from the beginning, it was difficult for him to adapt," said the Tottenham manager.

"We hope that that hat-trick helps him to feel more free, be more natural and become an important player and can help us to the end of the season."

Llorente has plenty of competition now just for a spot on the Tottenham bench and he needs more nights like this, against tougher opponents, to catch his manager's and the fans' attention again and convince people that time has not robbed football of the striker who once played for Atletico Blibao, Juventus, Sevilla and Spain.
